My fiancé plus our two friends and I highly recommend Klass’ place!
Klass provides such a great place to stay - so comfortable and it has everything - comfortable beds, great AC, comfortable couch and kitchen dining table plus chairs, kitchen supplies and dishware of all kinds, shampoo and soap, great water pressure, TV, and best of all - washer and dryer with detergent plus iron and board. We kind of wished we had skipped Phuket and just stayed here longer. We stayed at a great place later in Sukhumvit too, but this place felt more like home to us.
The location is amazing - it’s in Silom, a business district with so many things that cater to all of the local workers, especially the market and food court (Hong Kong Plaza) directly downstairs and to the right. There are so many amazing food options from 7AM to 3PM, including our favorites of our entire Thailand trip - the meatball skewer cart with the spicy and sweet chili sauces directly around the corner of the front door to the complex, the mango smoothies in the food court, the fruit stands, and the pork three ways (crispy pork belly, bbq, and sausage with rice). The best plate lunch though is in the food court and is on the left corner that serves many types of meat (e.g. chili, garlic, lemon verbena pork) and vegetable dishes (just look for the line of locals). Many massage places across the street too (a great one across the street and right at the base of the pedestrian walkway), and a 7-11 directly downstairs for all the Chang beers, coffees, and waters you could need.
Last but not least, the service staff. My fiancé accidentally left his cell phone in our Grab taxi when we first arrived and the app wouldn’t let us make a direct request to contact the driver or file a missing phone report. The concierge on the second floor spoke English and spent a long time helping us to locate the phone. We got it back an hour later, and we were so thankful for him because otherwise he would have been screwed. In addition, the security/doorman on the first floor (the day shift guy) was so friendly as he greeted us daily and helped us several times to get a taxi and negotiated a good rate for us too. He went so far as to stand in the middle of the busy street with scooters all having to dodge him just to get us a taxi! He was such a nice guy and he also made our stay amazing.
Don’t hesitate and book this place already. This was our first time in Thailand and Klass was super responsive and wanted to make sure our stay was seamless, which it really was. It went beyond what we expected, and we would all definitely stay again next time we visit Bangkok.
